1. **State the problem:** We are given the equation $4t + 0 = 4t$ and need to identify the property it illustrates. 2. **Recall the relevant property:** The equation shows that adding zero to any number does not change its value. This is known as the **Additive Identity Property**. 3. **Explain the property:** The Additive Identity Property states that for any number $a$, $a + 0 = a$. 4. **Apply to the problem:** Here, $a = 4t$, so $4t + 0 = 4t$ confirms the property. 5. **Final answer:** The equation $4t + 0 = 4t$ demonstrates the **Additive Identity Property**.
